How to Use This Calculator

Using this auto loan calculator is simple:

Enter the loan amount you're considering (e.g., $25,000)
Input the current interest rate offered by Navy Federal Credit Union (typically between 3% and 8%)
Select the loan term in years (common options are 3, 4, 5, or 6 years)
Click "Calculate" to see your estimated monthly payment, total interest, and total cost of the loan

The calculator will display your monthly payment, total interest paid over the life of the loan, and the total amount you'll pay back. You can also see a breakdown of how much principal and interest you'll pay each month.

Formula Used

The auto loan calculator uses the standard auto loan payment formula:

Monthly Payment = P × (r(1 + r)^n) / ((1 + r)^n - 1)

Where:

P = Principal loan amount
r = Monthly interest rate (annual rate divided by 12)
n = Number of payments (loan term in years × 12)

This formula calculates the fixed monthly payment required to fully amortize the loan over the specified term. The calculator then uses this monthly payment to determine the total interest paid and the total cost of the loan.

Worked Example

Let's look at an example to see how the calculator works:

Suppose you're considering a $20,000 auto loan with a 5.5% annual interest rate for 4 years (48 months). Here's how the calculation works:

Input	Value
Loan Amount	$20,000
Annual Interest Rate	5.5%
Loan Term	4 years

Using the formula:

Monthly Payment = $20,000 × (0.055/12 × (1 + 0.055/12)^48) / ((1 + 0.055/12)^48 - 1)

Calculating this gives a monthly payment of approximately $442.45.

Over 4 years, you would pay a total of $21,217.44, with $1,217.44 going toward interest.
